A server manages first time at which a configuration of a client apparatus is changed, while associating the first time with the client apparatus. The server obtains information indicating second time at which previous synchronization processing of a setting value is performed with the client apparatus. In the case where the second time is after the first time, the server sends, in response to a reception of a request for a setting value from the client, the client apparatus a setting value which is updated after the second time and type of which corresponds to the changed configuration of the client apparatus. In the case where the second time is before the first time, the server sends, in response to a reception of a request for a setting value from the client, the client apparatus setting information including a setting value which is not updated after the second time.
